Distributive Property

We worked today on the distributive property. While it is my favorite property, it is challenging. If your child is feeling like he/she does not understand this property, here are some resources you can use.

I hope this helps. Also, let your child know that today was the first day of distributive property. We will do a lot more practice!!!

Properties of Multiplication Definitions

Multiplication Properties There are four properties involving multiplication that will help make problems easier to solve. They are the commutative, associative, multiplicative identity and distributive properties. Commutative property: When two numbers are multiplied together, the product is the same regardless of the order of the multiplicands. For example 4 * 2 = 2 * 4 Associative Property: When three or more numbers are multiplied, the product is the same regardless of the grouping of the factors. For example (2 * 3) * 4 = 2 * (3 * 4) Multiplicative Identity Property: The product of any number and one is that number. For example 5 * 1 = 5. Distributive property: The sum of two numbers times a third number is equal to the sum of each addend times the third number. For example 4 * (6 + 3) = 4*6 + 4*3

Properties of Multiplication

This week we are focusing on the communtative and associative properties of multiplication. Next week we will learn about the distributive property. Please study the definitions of these properties with your child. We will have a test over them on Friday, October 11th.
